.SPECIFIGATIGNVforming part of Letters Patent No. 721,747, dated March 3, 1903. Application filed May 10,1902. Serial No. 106,743. (No model.)

To all whom/it nwty concern,.-

Beit known that I, JOSEPH ROEMER, a citi zen of the United States, residing at Santa Maria, in the county of Santa Barbara. and State of California, have invented certain new and useful Improvements in the Construction of Buildings; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art'to which it appertains to make and use the same.

This invention has relation to walls constructed of concrete and like self-setting materialcapable of use in the construction of buildings, the purpose being to acquire strength, durability, andto provide an embeddedv bond ofnovel formation and efficiency to hold the structure even though the wall The invention consists of the novel structural features, which hereinafter will be more fully described and claimed and which are shown in the annexed drawings,'in which- Figure l is a vertical transverse section' showing a portion of a concrete Wall embodying the invention and theformer and bond in position for another portion or section of the Wall.l Fig. 2 is. a perspective View of a section of concrete wall embodying the invention, a corner portion beingbroken away to show more clearly the frame and a part of the meshy bond attached thereto. Fig. 3 is a per? spectiveview'of the frame and meshy bond applied to opposite sides thereof.

Corresponding'and like parts'are referred to in the following description and indicated in all the views of the drawings by the same reference characters. Y

In accordance withl this invention a frame comprising uprights l and 2 and upper and lower beams 3 and 4 is provided, and a meshy bond is attached to each side of the frame,v

said frame and the attached meshy bond being embedded'in the concrete Wall 4, as illustrated most clearly in Figs. l and 2. The meshy bond may be of any open-work material so long as spaces are provided for the passage of thematerial from one side to the other of the bond. The frame may be of any size,

according to the section of wall to be constructed, and the meshy bond is appliedl to opposite sides thereof. The frame may be constructed either of Wood or metal, or a combination of the two materials, and the end portions of the upper beam 3 project beyond the 5`5 uprights to be engaged by any convenient support to hold the frame in position during the formation of the wall.

While the meshy bond may be of any construction, it is preferred to form it of wires 6o spaced apart any desired distance and arranged to cross' one another and attached at their ends to corresponding frame-bars. The wires 5 are vertically arranged and are secured to the. beams 3 and 4 by nails or other 65 means, and the wires 6 extend horizontally and are attached to the uprights l and 2. To give additional strength, diagonal wires 7 extend from opposite corners of the frame.

The frame is set up and is inclosed by sides 7o 8which constitute a former and serve to retainthe concrete in place. The frame, with the meshy bond attached thereto, occupies a central position between the sides 8, and the space between said sidesris filled in with con- 7 5 crete, thereby embedding the frame and the meshy bond, the concrete passing through the spaces formed between the several wires or openings of the meshy bond. After the y concrete has set the former or sides 8 are re- 8c moved, as indicated in the lower part of Fig. 1,'and another frame is placed in position `and the former set up, as indicated in the' up- 'being secured attheir ends to corresponding frame-bars, diagonal strengthening-Wires se-` cured to the frame and adapted to bear against and support the aforesaid meshy bond against x oo outward pressure, substantially as set forth.

In testimony whereof I affix my signature in presencevof two witnesses. A
